Our portable air compressors
are heavy-duty 7 HP air compressors with a diesel engine that provides proven
reliability and durability with a quad cylinder, cast iron, oil lubricated pump
for longer life and automatic idle control for reduced fuel consumption.
A ball valve drain allows for quick and thorough tank draining. An oversized flywheel
for extra cooling and pneumatic tire improves worksite mobility. Low profile design
for easy maneuverability and high-flow air-regulator for more work at higher pressure.

The ETQ air-cooled
diesel air compressors are widely used when electrical power is scarce. Air compressors
provide a portable mobile solution in supplying a pneumatic air supply for field
operations during project construction.

This
manual will explain how to operate and service your air compressor set.

If
you have any questions or suggestions about this manual, please contact your local
dealer or us directly. Consumers should notice that this manual might differ slightly
from the actual product as more improvements are made to our products. Some of
the pictures in this manual may differ slightly from the actual product as well.

PREPARATION
BEFORE OPERATION

Before starting the
air compressor, verify the following conditions.

AIR
COMPRESSOR OIL

 Fill the air compressor heat
with SAE10W-30 viscosity oil. Running the air compressor without oil will cause
severe damage to the air compressor head.

ENGINE
OIL

 Fill the engine with SAE 15W-40 engine oil
for general use or follow the table below.

Make
sure the air compressor is on a level surface and make sure the oil dipstick is
on tight.

FUEL


Add diesel fuel number 2 and never fill the fuel tank indoors. Also, be sure to
install the fuel tank cap on tight after filling.


DO NOT overfill the fuel tank. Always allow room for fuel expansion.


Never fill the fuel tank when the engine is running or hot. Allow the unit to
cool for two minutes before refueling. DO NOT light a cigarette or smoke when
filling the fuel tank.

AIR CLEANER

 Remove the wing nut holding down the air
cleaner cover.

 Remove the air cleaner cover and
air filter.

 Check the air cleaner element to be
sure they are clean and in good condition.


If the air filter is dirty, remove and clean the element.


Wash in solvent

 Squeeze


Soak oil

 Squeeze dry

 Reinstall the air cleaner element and secure the cover by
setting the cover spring.

BATTERY
(only for electric start models)

Check
to make sure that the battery acid level in each cell is between the upper and
lower limits.

(1) Upper limit

(2)
Lower limit

PRESSURE CONTROL VALVE

 Put the control valve is in the up position
before starting the air compressor.

STARTING
THE AIR COMPRESSOR

RECOIL STARTING

Note:
When the engine is running, do not pull the recoil handle, otherwise the engine
may be damaged.

DIESEL ENGINE WITH ELECTRIC
STARTER SYSTEM

Starting

The
preparation of the diesel engine for the electric starting system is the same
as the manual recoil type.

 Open the fuel
valve.

 Turn the start switch clockwise to the
"Start" position.

 If the engine is
started, immediately remove your hand away from the key switch.


If the engine does not start after 10 seconds, wait awhile (about 15 seconds)
before trying to start the engine again.

Battery

 Always check the liquid level of the battery
every month, if the level is lower than the low limit mark, refill the battery
with distilled water till you reach the upper limit mark.

COLD
STARTING

If the engine is difficult
to start in winter, take the rubber seal plug off and put 2cc of machine oil into
the hole.

Notice: Engines supplied to
the Torrid Zone will not contain the rubber plug. A solid plug is provided instead.

If the liquid level in the battery
is to low, the electric starter will not function to its best potential. Always
keep the level of the liquid in the battery between the upper and lower limits.
If there is too much liquid, the liquid will splash onto other nearby parts thereby
ruining the battery.

If you run the
starter motor to long, the voltage of the battery will drop and the motor may
be damaged. Keep the key switch in the "ON" position when the engine
is running.

Warning:

Never
remove the oil plug unless youre planning on filling the oil. If the plug is
not in place, rain, dust, and other impurities may be sucked into the engine causing
serious damage to the engine parts.

Never
use flammable liquids as fuel, such as gasoline etc. Also, never take away the
air cleaner for easy starting of the engine, doing so may cause explosions from
the intake gases.

STOPPING THE ENGINE

 First, bring down the speed of the engine
by using the speed governor. Let it run for 3 minutes at no load before stopping
it.

 Then stop the engine.

 Set the fuel cock at "S" (stop position)

 If the engine comes with an electric starter, turn the
starting switch to the "Off" position.


Pull the recoil handle slowly until pressure is felt by your hand, this means
the piston is on the compression stroke; where the intake and exhaust valves are
closed and then let the handle recoil back into the engine. This natural position
will prevent rust from occurring when the engine is being stored for long periods
of time.

Note: Only perform step
5 when the engine is off. Doing so otherwise will damage the engine.

Sudden
stops to the engine will cause abnormal temperature increases in the block of
the engine. Decrease the load gradually when stopping the engine. Also, never
stop the engine with the decompression lever.

MAINTENANCE
AIR COMPRESSOR

Check the oil level of
both the engine and air compressor head daily before operating the air compressor.

Below is a routine maintenance schedule.

DRIVEBELT

Belts
will stretch in normal use. A properly adjusted belt will deflect ½ inch with
a 5 pound force. To adjust the belt tension, follow the procedures below.

 Remove the belt guard.


Loosen the four fasteners holding the engine to the base-plate.


Shift the engine in the proper direction so that the desired tension is achieved.

 Align the belt and pulleys before tightening
down the engine.

CLEANING
THE AIR COMPRESSOR

Air compressor maintenance
consists of keeping the unit clean and dry. Be sure to store the unit in a clean
and dry environment, where it will not be exposed to excessive dust, dirt, moisture
or any corrosive vapors. Cooling slots should always be clean and free from clogs.

Note: Do not use a garden hose to clean
the air compressor. Water can enter the fuel and intake system and cause problems.

 To clean the air compressor, use a damp cloth
to wipe the exterior surfaces.

 Use a soft bristle
brush to loosen caked on dirt of oil.

 Use a vacuum
cleaner to pick up loose dirt and debris.

 Compressed
air (not to exceed 25 psi) may be used to blow away dirt.

STORAGE

Please follow the instructions below
if you plan on storing the air compressor for long periods of time.

 Run the engine for three minutes to burn out the excess fuel
in the chamber.

 Quickly drain away the engine
oil lubricant before the engine becomes cool and refill it with new oil. The figure
below shows where the oil plugs are located.


Take the rubber plug off the cover of the rocker shaft and put about 2cc of lubricant
into it and put the plug back in place. The figure below shows where to access
the plug.

 For recoil starting
engines, push the decompression lever down and pull the recoil starter two or
three times. This pushes all the excess intake mixture out of the combustion chamber.

 For engines that come with an electric starter,
hold down the decompression lever and turn the start key switch to the start position.
Let the engine rotate for about two to three seconds. Once again, this pushes
all the excess intake mixture out of the combustion chamber.


Now pull the decompression lever up and pull on the recoil starter slowly until
you feel resistance. The resistance point occurs on the compression stroke where
the intake and exhaust valves are closed. It is also the point that will prevent
moisture from entering the chamber to cause rust.


Finally, clean excess oils from the engine and put the engine in a nice dry place.

Normal wear:

Engines
and generators, like all mechanical devices, need periodic parts service and replacement
to perform well. Warranty will not cover repair when normal use has exhausted
the life of a part of an engine.

Improper
maintenance:

The life of an engine
or your equipment depends upon the conditions under which it operates, and the
care it receives. Some applications, such as tillers, pumps, and rotary movers,
are very often used in dusty or dirty conditions, which can cause what appears
to be premature, wear. Such wear, when caused by dirt, dust, spark pug cleaning
grit, or other abrasive material that has entered the engine because of improper
maintenance is is not covered by warranty.
